To forgive purely because it is nicer to forgive, and to do so when its a tough call; to try to speak only kindly of those we know because it is preferable to do so; to enjoy the successes of others because living thus is more enjoyable than the stress of living resentfully: such kind things make us better, lovlier people. And to try to live this way for its own merits, without invoking a supernatural reason for doing so, is to celebrate our humanity and to give kindness back its teeth.
